State di Vi'asiiin'gton, have invented certain new and useful Improvements in Ore Se arators and Concentrators, of which theiol-v lowing is a specification.

Referring now to the accompanying drawings in whichlike numerals of referenceindicate like parts throughout: Figure 1 is a View inlongitudinal section of an apparatus embodying my invention in -a form now preerred by me. Fig. 2 is .a top plan, view thereof with parts broken away, .and Fig. 3 f isa ragmentary v1ew,:onlarge scale, illustrating .more particularly one .of .the table adjusting devices.

The table 13, as now considered, is in the form of an endless apron invention receptacles lor tank-s l and y2 are provided, the former being the larger and having communication,

comparai which passes over a'suitable drive roller 15, and guide rollers 16, the latter of which are journaled in a :swing frame I7. Swing frame 17 which comprises 3suitably spaced side members, is 'supported for swinging-by legs l8'and arms .19, the :former being jou-rnaled Von a shaft4 20, having fixed thereto A if drive rollers l5, and having pivotal connec- My invention relates to apparatus of the@ above type and aims primarily to provide a construction wherein separation der its major tion with the upper portion'of trame 17 as will be' hereinafter more fully-set forth. .Arms `1,9 are pivotally connected with the lower `Aportion of .frame 17 and with carriersv n v 21, the latter being' controlled-"by suitable Other objects will be set forth as the description progresses and those ffeatures ofl means, as .screws v2,2, mounted on opposite walls of tank-,or receptacle A1, whereby said `frame can "be ad'justedto vary the inclination of tablevl. IAs. now considered, the pivotal connection .betweenflegs 1&8 and frame 17 is afforded by'the .end portions oli' theshaft 'of the uppermost .guide roller 16v being mounted in suitable blocks 23, slidably mounted in slots, formed in the sidel members of said frame, (see Fig. 3,) which blocks are engaged by adjustin screws 124:, .throuh .the .medium 'of which said blocks can e .ad-

efer'ence numeral 25 indicates 'an amalgamated plate which is arranged a suitablel soas to lie in a plane substantially parallel 1 and 2 can obwith theactive run of the table.

Reference numeral 28 indicates a drive shaft to which power is applied, as by a belt (not shown) passing over pulley 29. Power is transmitted from drive shaft 28 by cha-ins 30 and 31, which pass over suitable sprocket wheels, as shown, to Shafts 20 and 32 Arespectively, theV latter being provided with cranks or' eccentrics 33 to which .lin-'ks v 34. 'are connected. Links 34 arelalso pivotall'y connected lto 'fratrie I7, 'whereby upon rota` tion of 'shaft 32 cated. v

Then Reference numeral 35 indicates a fan or blower, operated from shaft 20 by a belt 36, which forces air through a pipe to the head 37, which head is arranged diagonally 'across thetop of tank or receptacle l and formed with a plurality of apertures (see Fig. 2) arranged to direct the air for discharge toward opening 11.

In tank or receptacle 2, l mount for rotation whatl I term araker 38, the same being driven from shaft 28 by a belt 39.

In operation gates 10 and l1 are closed and .water from any suitable source (not shown) is allowed to dow into tank 1 and indicated at X (see Fig. l) is reached which as will be observed, is considerably above the amalgamated plates. The mechanism is set inoperation, table 123 being run at a slow rate of speed while the 'reciprocation ot' terial tc be treated, received, as from a stamp mill, is now fed in any desired manner from a point over plate `25, so' as tol before reaching said plate, be com-I pelled to vtravel to a fair depth into the Water. During this step of the operation any substances 'of a greasy or oily nature will float with the flaky and rusty gold and not reach the'amalgamated plates, the heavier for example,

ingredients however alling'by gravity with the exception of the free gold which will be caught by one or thepther of plates 2Q and 27,`travels over plate25,through opening 26 onto plate 27 and then' onto table 13, which traveling upwardly .will carry thel heavier concentrates for discharge into' chamber 11i. By inclining the amalgamated lates, as descpi/oed, and supportin r the same `or swinging, the Water is agitata and will wash any foreign substances 'from the collected tree old, and also wash thelighter substances trom table 13. Further, .it will be observed that amalgamated plate 25, being inclined downwardly toward table 13, will during its movement so act on the Water as to produce waves which will travel well upon the upper portion of the table, and serve to further cleanse the concentrates beingconveyed Ato chamber lei. Air discharged from head 37 forces the float toward gate l1', which may be opened upwardly when desired to permit tl1e,tloat to iow into tank 2,`where itis moved by raker 38 from about the gate l1 to the opposite end portion ofthe tank. ln tank 2, the float is allowed to stand until the preciousY ingredients fall and collect at the by opening gate 10 downwardlyfth'e oily substances can again be permitted to enter tank l. Sand, gravel and 'any other foreign substances falling from the lower end portion of table i3 will collect about the discharge opening 9, where l senses they will discharge with the outtlowing water upon the opening of valve 8.

` Having thus described my invention, what .l claim` as new, and desire tosecure by llctters Patent of the United. States of America., 1s:

l. An or'e separator comprising a tank adapted to contain water, a frame mounted for reciprocation in said tank, an endless apron mounted on said frame in an inclined position, means to operate said apron so that the upper run thereof will move upwardly during movement of said frame, and amulgamating means comprising reversely inclined members arranged one above the other, the upper of' said members being formed in its lower portion with a discharge opening and the lower of said members being fixed to the lower edge ortion ot saidy upper member beneath the ischarge opening thereof.

2. An ore separator comprising a tank adapted to contain water, a frame mounted for reciprocation in said tank, an endless apron mounted on saidirame in an inclined position, means to operate said apron so that the upper run thereof will move upwardly during reciprocatorymovement of said frame, and amalgamating means connected for movei'nent' with said frame, comprising reversely inclined members arranged to be normally submerged and ositioned one above the other, the lower or said members being positioned to receive material vtrom the upper one and to discharge onto the upper run of said apron.

3. An. ore separator comprising a. tank adapted to contain water, an endless apron arran ed in anA inclined position and supporte for swinging in said tank, said apron being disposed so as to have its upper portion normally arranged out of the wateigand an inclined amalgamating plate arranged in said tank and connected to be moved during `swinging of said apron for forcing water upwardly thereof.

4. An ore separator comprising tanks having a pair of communicating openings, vertically s'lidable gates for the openings ct said tanks, said gates being supported :for sliding in relatively opposite directions for movement to their open positions, ainalgumating means arranged in one ci said tanks so as to be normally submerged, and means for forcing matter lioating on the water in said last named tank toward one of the openings thereof for discharge into the other tank.

5. An ore se arator comprisingtanks having a pair o' their upper portion, gates for the openings of said tanks, amalgamating means arranged in one of vsaid tanks so as to be. normally sul;-

onto the unsubmergcd portion comn'iunicating openings al lili opening of said tanks merged, means for 'directng air for @iseharge toward one of the communicatmg opemngs of said. tanks for impellng the float therethrough, and means in the other tank for causing the float received therein to travel toward the other communeting and collect therenbout, whereby upon opening. of the gate controlling said opening, the oilyls'ustances Wilbe impelled back into said rst named 10 tan Signed at Georgetown, 10 day of August 1908.
